Detailed Description
The present invention will be described in further detail with reference to preferred embodiments.
The preparation method of the special high-dispersion white carbon black for the high-ice-surface-grip tire comprises the following steps: and in the presence of electrolyte and glycerol trioleate, reacting sodium silicate with an acidifying agent to obtain the white carbon black.
The method comprises the following specific steps:
(1) firstly, adding an electrolyte solution into a reaction kettle, and heating to 60-65 ℃;
(2) then adding a sodium silicate solution into the reaction kettle, adjusting the pH value to 9-10, and heating to 70-75 ℃;
(3) then glycerol trioleate is added into the reaction kettle;
(4) then adding a sodium silicate solution and an acidifying agent into the reaction kettle, controlling the pH value to be 10-11, and heating to 90-95 ℃ after the addition is finished;
(5) and continuously adding an acidifying agent, adjusting the pH value to 5-6, preserving heat, washing and drying to obtain the white carbon black.
The Zeta potential of the crystal grains can be regulated and controlled by adding the electrolyte, so that the reaction of the sodium silicate and the acidifying agent is promoted.
As one of the preferable technical solutions of the present invention, the electrolyte is selected from sodium sulfate.
In some preferred embodiments of the present invention, in the step (1), the electrolyte solution is added in an amount of 1/6 to 1/7 of the volume of the reaction kettle.
In some more preferred embodiments of the present invention, the electrolyte solution is a 5 wt% sodium sulfate solution.
As one of the preferable technical proposal of the invention, the acidifier is selected from sulfuric acid or hydrochloric acid.
In some preferred embodiments of the present invention, the amount of triolein is controlled to sodium silicate (as SiO)2Calculated) 0.5 to 5 per thousand of the weight, specifically such as 0.5 per thousand, 0.8 per thousand, 1 per thousand, 1.5 per thousand, 2 per thousand, 3 per thousand, 4 per thousand, 5 per thousand. The triolein is easy to foam when the dosage is more than the dosage, thus influencing the operation, and the dosage is less than the dosage, thus the effect of reducing the agglomeration probability of crystal grains can not be achieved.
In some preferred embodiments of the invention, in the step (4), the sodium silicate solution is stopped to be added when the volume of the reaction solution accounts for 2/3-3/4 of the volume of the reaction kettle.
In some preferred embodiments of the present invention, the concentration of the sodium silicate solution is 10 to 30 wt%, specifically, 10%, 15%, 20%, 25%, 30%. When the sodium silicate solution is higher than the concentration range, the agglomeration probability of the white carbon black is obviously increased, and when the sodium silicate solution is lower than the concentration range, the energy conservation and consumption reduction of the post-treatment of the white carbon black slurry are not facilitated.
In some preferred embodiments of the present invention, in the step (5), the temperature is maintained at 90-95 ℃ for 0.1-1 hour.
In some preferred embodiments of the present invention, the stirring speed of the reaction kettle is controlled to be 60-100 rpm.

BET is 100 to 130m2/g，
The dispersion grade is more than or equal to 9.5,
the loss factor tan delta @ 20 ℃ of the corresponding vulcanized rubber is more than or equal to 1.0.
Compared with the commercial white carbon black, the white carbon black disclosed by the invention can improve the average deceleration of the rubber tire on the ice ground by more than 20% under the same addition amount, and the ice surface gripping force is obviously improved.

(1) Adding a sodium sulfate solution with the concentration of 5 wt% into the reaction kettle, wherein the volume of the sodium sulfate solution is 1/6 of the volume of the reaction kettle, starting a stirrer (60 revolutions per minute), and heating to 60-65 ℃;
(2) then adding a sodium silicate solution with the concentration of 20 wt% into the reaction kettle, adjusting the pH value of the system to 9-10, and heating to 70-75 ℃;
(3) then glycerol trioleate (CAS:122-32-7) is added into the reaction kettle, and the added amount is sodium Silicate (SiO)2Calculated) 1 per mill of the total addition;
(4) then adding a sodium silicate solution with the concentration of 20 wt% and a sulfuric acid solution with the concentration of 10 wt% into the reaction kettle, controlling the pH value of the system to be 10-11 in the adding process, stopping adding the sodium silicate after the reaction liquid reaches 2/3 of the volume of the reaction kettle, and heating to 90-95 ℃;
(5) continuously adding a 10 wt% sulfuric acid solution, adjusting the pH value of the system to 5-6, and reacting for 15 minutes in a heat preservation manner.
